The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational psychology, cognitive load theory suggests that learning is most effective when instructional materials are designed to minimize extraneous cognitive load, allowing learners to focus on intrinsic load and germane load. Intrinsic load is the inherent difficulty of the material itself, while germane load is the effort devoted to processing and understanding the information. Overly complex presentations, such as redundant text and visuals, can increase extraneous load, hindering comprehension. Conversely, well-structured materials that integrate diagrams with concise explanations can reduce unnecessary mental effort, facilitating deeper learning. This theory has significant implications for curriculum design, particularly in STEM fields where abstract concepts are prevalent.
